The invention relates to modulating Cdc14B levels (cell division cycle 14 homolog B) and/or Cdh1 (Fzr1 protein, CDC20-like 1b, or fizzy-related protein) levels to sensitize cells to DNA damage by increasing the abundance of Plk1 (polo-like kinase 1) in a target cell. In certain embodiments, the invention relates to modulating Plk1 levels, and in particular to increasing Plk1 levels, to sensitize target cells such as cancer cells to cell death or apoptosis. In certain embodiments, the invention relates to inhibitors of Cdc14B and Cdh1 that sensitize tumor cells to chemotherapy or radiation induced cell death or apoptosis. In addition to applications relating to cancer therapies and diagnostics, the Plk1 modulators and assays will be employed for identifying novel drugs or drug candidates useful for various proliferative and/or differentiative disorders such as major opportunistic infections, immune disorders, cardiovascular diseases and inflammatory disorders.

The invention relates to application of a micromolecule interference RNA to the preparation of medicines capable of regulating and controlling the tumor cell division cycle. The micromolecule interference RNA can submerge the survivin gene expression, regulate and control the cell cycles of the lung cancer, the gastric cancer, the hepatic cancer, the breast cancer and the cervical carcinoma with high efficiency, and remarkably inhibit the division of the cells of the lung cancer, the gastric cancer, the hepatic cancer, the breast cancer and the cervical carcinoma. The micromolecule interference RNA can be used for preparing the medicines capable of inhibiting tumor cell division.

The present invention relates to uracil glycosidase process for detecting cell division cycle protein gene 6 in tumor. In the process of DNA extraction, RNA extraction, protein extraction, immunohistochemistry, reverse transcription (RT), PCR, Northern hybridizing, in-situ hybridizing and capillary electrophoresis, uracil glycosidase process is adopted for detecting cell division cycle protein gene 6 in tumor. The process has dU to replace dT in synthesizing the first pair of reactants, uracil glycosidase treatment before the second amplification to eliminate the residual pollutant of PCR product, and dUTP to replace dTTP in the second amplification for mixing great amount of dU into the product. The process can eliminate all pollutants of different sources.

The invention relates to a bathing box capable of prolonging life. The bathing box combines a physical mode, a chemical function and psychological induction together. In the aspect of the physical mode, the bathing box can perform mechanical sealing, heating, skin expanding through vacuum and free radial suction through negative pressure. In the aspect of the chemical function, Chinese medicinal herb bathing agents having the function of achieving composite displacement with the free radial (heavy metal toxin) are utilized. In the aspect of the psychological induction, popular science films and light music of the bathing box capable of prolonging the life are played. When the bathing box capable of prolonging the life is used, the popular science films and the light music can stimulate the brain and activate the skin so that under the vacuum state, skin cell sizes are enlarged, and capillaries are expanded. In addition, active ingredients of Chinese medicinal herbs enter the skin to react with the free radial containing heavy metal, and the free radial can be effectively separated from cells and is removed out of the skin, so that activity of the skin is recovered, immunity is improved, a cell division cycle and cell life are prolonged, and the purpose of rejuvenation and longevity of people is achieved.

The invention discloses a demethylation-based vector for promoting self-renewal and proliferation of germline stem cells and application thereof. The vector is coated in slow virus, and carries mTet1 gene. The vector is a slow virus vector, and the nucleotide sequence of the mTet1 gene is disclosed as SEQ.ID.NO.1. After the vector disclosed by the invention is exprssed through the slow virus, the mTet1 gene is integrated to the genome of the milk goat male germline stem cells. When the stable positive cells are cultured, the cells grow in a swirl cluster mode and have favorable cytomorphology; the stream-mode analysis on the cell division cycle detects that the quantity of S-stage cells is increased, which indicates that the proliferation capacity is enhanced; and the transcription level detects that the expression of the male germline stem cell related gene and self-renewal related gene is increased, and the expression of the differentiation related gene is decreased.
